This are all speculations, feeded by rumors and the latest PC laptops.
case Apple always said the 12” Macbook is the “future of the notebook”. So it’s clear that the new Pro`s will look like bigger brothers of the 12”. The thing I like the most of the 12” is the color! Space grey on a Macbook looks awesome! It’s darker than the normal aluminum unibody. They should just add more than one USB-C port…
I first used boot2docker as docker platform for Mac OS X. With Boot2docker it’s hard to customize stuff, because it’s not build for that purpose.
Once I tried to put a desktop app into a docker container with 3D hardware support. The 3D performence was really bad…
VirtualBox isn’t the best virtualization platform for this. When using boot2docker with Virtualbox I always thought this should/could perform a bit faster. See also my entry about file sharing in docker.
For my next linux servers I’m exploring zfs as storage option. There is some stuff on zfs which you need to decide on zpool creation. This can’t be changed later without destroying your data.
The block size of the filesystem is one of these. In zfs this is named ashift. With this property you can balance the space which very small files take and the MB/s you get when reading very big files.
